St-70 upgrades

The best example of why NOT to use incorrect connectors: people who used to use regular household plugs/jacks on their SPEAKER WIRES for easy connect/disconnect.

This should get you some jacks to look at. They will be close to what I pictured. It appears that I purchased some left over stock from a local electronics shop that they discounted. The number I have on my box is 256 103 Jack and it doesn't seem to play.

Side note here* I used insulated washers on both sides of the chassis. If you laid out your hole centers at .750 then a common banana jack can be inserted into both the neg and positive jacks at the same time. One step further would be to make up a harness that plugs into your meter.

BTW, the referenced page link is for "tip" jacks (very similar to what I suggested previously). Those will fit standard test probes. If you prefer to use "banana" jacks go to this page link:

To each his own but this is my setup on one of my amps. A cheap $2 meter that is accurated and banana jacks set on a .750 c-to-c and a standard banana jack with meter leads will slide right in. The advantage to this setup is the meter probe tips will not accidentally come out. Just my .02
